CarSim simulates the dynamic behavior of passenger cars, racecars, light
trucks, and utility vehicles. CarSim animates simulated tests and outputs
over 800 calculated variables to plot and analyze, or export to other software
such as MATLAB, Excel, and optimization tools.

Easy to Use

With CarSim’s modern
graphical user interface, you can run a simulated test, see an animation,
or view engineering plots of results with just one mouse click. With the CarSim
Quick Start Guide you will be making new runs and seeing their results
in about an hour. See for yourself: here is the 11-part
video series for the Quick Start Guide (total
time is 65 minutes).

Output plots and animations are obtained with a single button click. Besides
being versatile and interactive analysis tools, the graphics they produce can
be easily inserted into reports and PowerPoint presentations.

The CarSim math models are parametric, involving measurable
properties that
are commonly used by OEM's and supplier companies. (This is in contrast to
esoteric multibody descriptions used in older simulation math models.) As a
result, CarSim users can usually get results for new vehicles with minimal
time.

Many Example Datasets and Animator Shapes

CarSim comes with over 15 vehicles: class A-F passenger cars, some vans, utility vehicls, and light trucks. There are many example test procedures, and over 20 3D vehicle shape files for quality animations. Each 3D vehicle shape is automatically resized as needed to match the dimensions set for the vehicle model, and the overall color can be reset at run time to help distinguish between overlays of vehicle from different simulated tests.

Accurate

The CarSim math models are built on decades of research in characterizing vehicles
and reproducing their behavior with mathematical models. Validation testing
continues as new features are added. OEM users consistently find close agreement
between CarSim predictions and actual test results.

Extensible

The CarSim math models cover the complete vehicle system and its inputs from
the driver, ground, and aerodynamics. The models
are extensible using built-in VehicleSim
commands, MATLAB/Simulink from
the Mathworks, LabVIEW from
National Instruments, and custom programs written
in Visual Basic, C, MATLAB, and other languages. Use these options to add advanced
controllers or extend the detail in subsystem or component models such as tires,
brakes, powertrain, etc.

Fast

CarSim combines a complete vehicle math model with high computational speed.
The software development team at Mechanical Simulation uses the VehicleSim
Lisp symbolic multibody program to generate the equations for
the vehicle math models. Besides providing correct nonlinear equations for
fairly complicated models, the machine-generated equations are highly optimized
to provide fast computation.

CarSim models typically run more than ten times faster than
real time on a 3 GHz PC, so you always get results quickly. CarSim easily supports real-time
(RT) testing with hardware in the loop (HIL) using systems from most
RT suppliers. This speed also helps with software that requires many repetitions
(optimization, design-of-experiments, etc.).

Cost Effective, Stable, Reliable

CarSim has all the tools you need to predict vehicle dynamics behavior in one
integrated package, with the capability of working with other software to extend
its capabilities even further. It combines the accuracy and validation resulting
from decades of research in vehicle dynamics with the ease-of-use associated
with modern video games and Internet browsers.

CarSim includes everything needed to simulate
vehicle tests and view the results, yet it is priced at a fraction of the
cost of other commercial vehicle dynamics software.
